Description
本發明係關於一種流體流動控制裝置；及在較佳的具體實例中，係關於一種具有插管(經常為針頭)之醫療裝置，其可***患者中以使用來輸液、收集或抽取流體。本發明的一個觀點係關於一種具有引動器之醫療裝置，其中該引動器可經操控以在輸液或抽取後修改在插管與外部流體來源或儲槽間的流體流動路徑。本發明之另一個觀點係關於一種機構，其當附加至流體流動線時作用為夾鉗。本發明的另一個觀點係關於一種機構，其在使用後插管會縮回裝置內以防止意外的針刺及防止受污染的插管再使用。雖然本發明對使用於血管內(“IV”)的應用特別佳，其亦可有益地使用例如在硬膜外、骨內及眼內應用中，及用於任何體液。The present invention relates to a fluid flow control device; and in a preferred embodiment, to a medical device having a cannula (often a needle) that can be inserted into a patient for use in infusion, collection or extraction of fluid. One aspect of the present invention is directed to a medical device having an actuator that is operable to modify a fluid flow path between a cannula and an external fluid source or reservoir after infusion or extraction. Another aspect of the present invention is directed to a mechanism that acts as a clamp when attached to a fluid flow line. Another aspect of the present invention is directed to a mechanism that, after use, can be retracted into the device to prevent accidental needle sticks and to prevent contamination of the cannula. While the invention is particularly preferred for use in intravascular ("IV") applications, it can be beneficially used, for example, in epidural, intraosseous, and intraocular applications, as well as in any body fluid.
血管內(“IV”)輸液組在技藝中已知，其藉由連接至管子的插管將流體及/或藥物輸送至患者。IV輸液裝置時常已附加側翼，以便在插管***期間的處理容易、幫助穩定該裝置及可穩固以限制該裝置在使用期間之移動。以相同原理來操作血液收集裝置，但是程序相反。經由插管(其通過該裝置的主體連接至血液收集儲槽)從靜脈或動脈收集血液。在使用習知的輸液或流體收集系統後，該插管會受血液及/或其它體液污染，及必需小心以避免再使用該裝置及避免附帶地刺到保健工作者或患者，因此散佈血液輸送性病原體。使用罩子或套子且在從患者上移開後必需將其放回插管上之方式並非令人滿意的解決辦法，因為它們會增加意外刺到的風險，或罩子會變鬆散及脫離，因此再次曝露出該受污染的插管。Intravascular ("IV") infusion sets are known in the art for delivering fluids and/or drugs to a patient via a cannula attached to a tube. IV infusion devices are often supplemented with wings to facilitate handling during insertion of the cannula, to help stabilize the device, and to stabilize to limit movement of the device during use. The blood collection device is operated on the same principle, but the procedure is reversed. Blood is collected from the vein or artery via a cannula that is connected to the blood collection reservoir by the body of the device. After using a conventional infusion or fluid collection system, the cannula is contaminated with blood and/or other body fluids, and care must be taken to avoid re-use of the device and to avoid incidental punctures to health care workers or patients, thus disseminating blood delivery Sexual pathogens. The use of a cover or sleeve and the need to put it back on the cannula after removal from the patient is not a satisfactory solution because they increase the risk of accidental stabs, or the cover becomes loose and detached, so again Expose the contaminated cannula.
蕭(Shaw)的U.S. 5,779,679發表名稱“具有可縮回的插管之加側翼的IV組”及蕭的U.S. 6,210,371發表名稱“加側翼的IV組”，二者皆揭示出一種具有可縮回的插管之IV輸液組。在這二篇專利中，該可縮回的插管由一在其背端部分上具有管狀連結器(其在插管與IV管間建立流體連通)之縮回成員支撐。該縮回成員由配置在外罩的相反邊上之可釋放的彈簧鎖對來抗對經壓縮的彈簧之力量而保持在其未縮回的位置中。一旦彈簧鎖被釋放，彈簧會將該縮回成員(因此該插管)推回外罩中。但是，因為IV管直接連接至該縮回成員，插管縮回使得IV管同樣向後移動。若該管子在縮回期間無法自由地向後移動時，該縮回成員及插管無法完全縮回。US 5,779,679 to Shaw, entitled "Group IV with retractable cannula plus flank" and Xiao, US 6,210,371, entitled "Flanking IV group", both of which reveal a retractable Intubation IV infusion set. In these two patents, the retractable cannula is supported by a retracted member having a tubular connector on its back end portion that establishes fluid communication between the cannula and the IV tube. The retracted member is held in its unretracted position against the force of the compressed spring by a releasable spring lock pair disposed on the opposite side of the outer cover. Once the snap lock is released, the spring pushes the retracted member (and therefore the cannula) back into the housing. However, because the IV tube is directly connected to the retracted member, the cannula is retracted so that the IV tube also moves rearward. If the tube is unable to move freely backwards during retraction, the retracted member and cannula cannot be fully retracted.
需要該插管可縮回而沒有造成或依賴連接管向後移動之輸液及流體收集裝置，且其與插管之縮回相關連的方式為該裝置提供無法再使用及該流體流動路徑被阻斷、重新安置及封鎖。There is a need for an infusion and fluid collection device that can be retracted without causing or relying on the backward movement of the connecting tube, and that is associated with the retraction of the cannula in such a way that the device is rendered unusable and the fluid flow path is blocked , resettlement and blockade.

從外罩12橫向延伸出選擇性的穩定側翼20，其讓使用者容易處理該裝置10。當使用時，側翼20亦提供一表面，當裝置10使用膠帶、縫合用線或其它類似有效的方法來穩固至患者時，其將限制外罩12旋轉。在如醫療所指定般已經給藥至患者或從其抽出想要的流體體積後，可藉由對引動器18的柄44之前側手動施加向後面方向的壓力同時同步地抓緊外罩12來終止通過插管14的流體流動及讓插管14縮回外罩12內。若必要時，插管14可縮回外罩12中而沒有先將其從患者中抽回。裝置10之使用及插管14之縮回將在下列相關的第2及3圖中更完整地討論。A selectively stabilizing side flap 20 extends laterally from the outer cover 12, which allows the user to easily handle the device 10. When used, the side flaps 20 also provide a surface that will limit rotation of the outer cover 12 when the device 10 is secured to the patient using tape, suture threads, or other similarly effective means. After the patient has been dosed or withdrawn from the desired fluid volume as specified by the medical procedure, the passage can be terminated by manually applying a pressure in the rear direction to the front side of the shank 44 of the actuator 18 while simultaneously grasping the outer cover 12 simultaneously. The fluid flow of the cannula 14 and the cannula 14 are retracted into the outer cover 12. If necessary, the cannula 14 can be retracted into the housing 12 without first withdrawing it from the patient. The use of device 10 and the retraction of cannula 14 will be discussed more fully in the following related Figures 2 and 3.
參照第2圖，所顯示出的裝置10沒有附加該選擇性穩定側翼。裝置10之外罩12包括二個包含下部分26與上部分28的伸長部分。下部分26進一步包括較小直徑的前端32及較大直徑的後端34，與由配置在前端32與後端34間之肩部30所定義的過渡區域。上部分28從在肩部30上之位置向後延伸至在下部分26之後端34上的開放式後端，其包含一提供作為管子部分24可***其中之連結器的縱向孔。想要藉由任何合適的方法將管子部分24的末端維持在外罩12之上部分28內，諸如例如，摩擦接合或使用鉗住裝置、黏著劑或其類似物。依裝置10之想要的用途而定，管子部分24可具有合適於將裝置10連接至流體來源(諸如IV袋)或流體儲槽(諸如血液收集系統)之任何想要的長度。下部分26進一步包含一配置在後端34與過渡區域肩部30間的縮回腔36較佳。如所顯示，縮回腔36的後端34包含一由端帽42所關閉之開口。下部分26進一步包含一孔洞38，其配置在過渡區域肩部30稍微向前之上壁中。孔洞38對齊在上部分28的底部中之孔洞40，及孔洞38,40之對準幫助在插管14與管子部分24間建立一流體流動路徑。Referring to Figure 2, the device 10 shown is not attached to the selective stabilizing flank. The outer cover 12 of the device 10 includes two elongated portions including a lower portion 26 and an upper portion 28. The lower portion 26 further includes a smaller diameter front end 32 and a larger diameter rear end 34, and a transition region defined by a shoulder 30 disposed between the front end 32 and the rear end 34. The upper portion 28 extends rearwardly from a position on the shoulder 30 to an open rear end on the rear end 34 of the lower portion 26, which includes a longitudinal bore that provides a connector into which the tube portion 24 can be inserted. It is desirable to maintain the end of the tube portion 24 in the upper portion 28 of the outer cover 12 by any suitable means such as, for example, frictional engagement or use of a clamping device, an adhesive, or the like. Depending on the intended use of the device 10, the tube portion 24 can have any desired length suitable for connecting the device 10 to a fluid source (such as an IV bag) or a fluid reservoir (such as a blood collection system). The lower portion 26 further includes a retracting cavity 36 disposed between the rear end 34 and the transition region shoulder 30. As shown, the rear end 34 of the retraction chamber 36 includes an opening that is closed by the end cap 42. The lower portion 26 further includes a bore 38 disposed in the transition region shoulder 30 slightly forwardly in the upper wall. The holes 38 are aligned with the holes 40 in the bottom of the upper portion 28, and the alignment of the holes 38, 40 helps establish a fluid flow path between the cannula 14 and the tube portion 24.
在下部分26的前端32處之開口由可滑動接合的管狀引動器18關閉，其中該引動器包含從前端邊緣向上延伸的柄44。引動器18可從第一位置(其中柄44與下部分26之前端32間隔開)移動至第二位置(其中柄44鄰接且毗連至下部分26的前端32)。引動器18想要製成縱長型，以便延伸進入外罩12的下部分26中一段足夠的距離，以便當引動器18移動至與前端32毗連之第二位置時可遮蓋及關閉在下部分26中的孔洞38。引動器18亦想要包含一從引動器18的後端向外延伸之對立相對的彈簧鎖對。當滑動端帽18朝向其第二位置移動時，彈簧鎖在上面滑動及嚙合在下部分26的內壁上之凸出肩部，因此將引動器18鎖在其第二位置中及防止其從外罩12中移出。The opening at the forward end 32 of the lower portion 26 is closed by a slidably engageable tubular actuator 18, wherein the actuator includes a shank 44 that extends upwardly from the leading edge. The actuator 18 is moveable from a first position in which the shank 44 is spaced from the forward end 32 of the lower portion 26 to a second position (where the shank 44 abuts and abuts the leading end 32 of the lower portion 26). The actuator 18 is intended to be elongated to extend into the lower portion 26 of the outer cover 12 a sufficient distance to cover and close the lower portion 26 when the actuator 18 is moved to a second position adjacent the front end 32. Hole 38. The actuator 18 also desirably includes a pair of opposed spring locks that extend outwardly from the rear end of the actuator 18. When the sliding end cap 18 is moved toward its second position, the spring lock slides over and engages the raised shoulder on the inner wall of the lower portion 26, thereby locking the actuator 18 in its second position and preventing it from exiting the housing Move out of 12.
縮回機構13裝載插管14且包含插管持器16、插管持器栓46及彈簧22。想要預先組裝插管持器16、彈簧22及插管持器栓46且經由在後端34中的開口及經由縮回腔36將其***下部分26中，接著將引動器18構形於下部分26的前端中。在***前，想要將有彈力的插管持器栓46摩擦接合***在插管持器16的較大直徑部分58內之凹處中。彈簧22想要放置在插管持器16的較小直徑前端部分上方，於此其向後滑入與環狀肩部52毗連接合。然後，定向該組合單元以便流體通道60與在下部分26的上壁中之孔洞38對準，及前進通過過渡區域肩部30。當插管持器16之向前延伸的尖端向前凸出引動器18時，彈簧22對著環狀肩部安置在引動器18的前端開口內及被壓縮至顯示在第2圖中之位置。引動器18抵擋壓縮彈簧的力量及藉由有彈力的彈簧鎖將引動器18穩固至外罩12，以防止其在彈簧力下向前移出外罩12，如先前描述般。當流體流過中空插管14及插管持器16而進入插管持器栓46中、通過在插管持器栓46之上部中的孔洞60、通過在縮回腔外罩26之上部中的孔洞38、通過在管子組合外罩28之底部中的孔洞40及進入管子24中時，此元件組態允許插管14與管子24流體連通。類似地，流體可以相反方向流動及從管子24通過，經由對準孔洞40、38及60及出去插管14。在構形插管14與插管持器栓46後，於下部分26之開口端中構形後端罩42，及摩擦地保持在下部分26的後端34內。The retraction mechanism 13 carries the cannula 14 and includes a cannula holder 16, a cannula holder 46, and a spring 22. It is desirable to pre-assemble the insertion tube 16, the spring 22 and the insertion tube stopper 46 and insert it into the lower portion 26 via the opening in the rear end 34 and via the retraction chamber 36, and then configure the actuator 18 to In the front end of the lower portion 26. Prior to insertion, the resilient cannula plug 46 is intended to be frictionally engaged in a recess in the larger diameter portion 58 of the cannula holder 16. The spring 22 is intended to be placed over the smaller diameter front end portion of the insertion tube 16, where it slides back into engagement with the annular shoulder 52. The combination unit is then oriented such that the fluid passage 60 aligns with the aperture 38 in the upper wall of the lower portion 26 and advances through the transition region shoulder 30. When the forwardly extending tip end of the insertion tube 16 projects forwardly from the actuator 18, the spring 22 is placed in the front end opening of the actuator 18 against the annular shoulder and compressed to the position shown in FIG. . The actuator 18 resists the force of the compression spring and secures the actuator 18 to the outer cover 12 by a resilient spring lock to prevent it from moving forward out of the outer cover 12 under spring force, as previously described. When the fluid flows through the hollow cannula 14 and the cannula 16 into the cannula holder 46, through the aperture 60 in the upper portion of the insertion tube hub 46, through the upper portion of the retraction chamber cover 26 The element 38 allows the cannula 14 to be in fluid communication with the tube 24 by the hole 40 in the bottom of the tube assembly housing 28 and into the tube 24. Similarly, the fluid can flow in the opposite direction and through the tube 24, through the alignment holes 40, 38 and 60 and out of the cannula 14. After the cannula 14 and the cannula holder 46 are configured, the rear end cap 42 is configured in the open end of the lower portion 26 and frictionally retained within the rear end 34 of the lower portion 26.
雖然插管14可在縮回機構13***外罩12中前以固定關係穩固至插管持器16，想要在插管持器16構形在外罩12內後，將插管14***插管持器16之凸出尖端的孔中。如在第2圖中看見，在插管持器16的向前延伸端處之開口呈錐形，以使插管14之***及附加容易。插管14可摩擦地保持在插管持器16的孔內，但是想要使用黏著劑或由一般熟知此技藝之人士已知的任何其它類似有效方法，以固定關係附加至插管持器16。想要插管14的斜面處之開口部分面向上，以便容易***患者中。如顯示在第2圖中，中空插管14的開口式後端62延伸通過插管持器16之後端58進入插管持器栓46的開口前端部分54。但是，應該察知的是，插管14僅需要延伸進入插管持器16中一段足夠的距離來促進在其之間有可信賴的接合。Although the cannula 14 can be secured to the insertion tube 16 in a fixed relationship prior to insertion of the retraction mechanism 13 into the outer cover 12, it is desirable to insert the cannula 14 into the cannula after the insertion of the insertion tube 16 within the outer cover 12. The projection 16 protrudes into the hole of the tip. As seen in Fig. 2, the opening at the forwardly extending end of the insertion tube 16 is tapered to facilitate insertion and attachment of the cannula 14. The cannula 14 is frictionally retained within the bore of the cannula holder 16, but is intended to be attached to the cannula 16 in a fixed relationship using an adhesive or any other similarly effective method known to those skilled in the art. . It is desirable that the opening portion at the slope of the cannula 14 faces upward for easy insertion into a patient. As shown in FIG. 2, the open rear end 62 of the hollow cannula 14 extends through the posterior end 58 of the insertion tube 16 into the open front end portion 54 of the introducer stem 46. However, it should be appreciated that the cannula 14 only needs to extend into the cannula holder 16 a sufficient distance to promote a reliable engagement therebetween.
當如上所述般組合裝置10時，經壓縮的彈簧22或任何其它類似有效的偏向加壓方法對插管14及插管持器16向後偏向加壓。由插管持器栓46對在下部分26的較小直徑前端部分之表面50內所施加的摩擦支撐力量應該足夠大，以便抵擋由彈簧22對著環狀肩部52所施加與在插管14***患者期間經由插管14及插管持器16返回插管持器栓46所施加的力量組合之偏向加壓力量。其它方面，插管14可能相對於外罩12過早縮回而沒有移動引動器18。When the device 10 is assembled as described above, the cannula 14 and the cannula 16 are biased rearwardly by the compressed spring 22 or any other similarly effective biasing method. The frictional support force exerted by the insertion tube stopper 46 on the surface 50 of the smaller diameter front end portion of the lower portion 26 should be sufficiently large to withstand the application of the spring 22 against the annular shoulder 52 and the cannula 14 The biasing force applied to the combination of forces applied by the cannula holder 46 via the cannula 14 and the cannula holder 16 during insertion into the patient. In other aspects, the cannula 14 may be retracted prematurely relative to the housing 12 without moving the actuator 18.
當該流體輸液或抽取程序完成時，使用者可藉由對柄44施加向後方向的壓力同時將外罩12維持在靜止位置中(藉由夾住其紋理化的外表面部分(可在第1圖中看見)或藉由向下壓在選擇性側翼(其可能已經穩固至患者)上)啟動縮回及讓插管14縮回。施加至柄44的手動壓力造成引動器18相對於外罩12向後移動。想要當插管(典型為針頭)仍然***患者中時啟動縮回。當引動器18向後移動時，插管持器16及插管持器栓46亦由於在引動器18之後端64與插管持器16的環狀肩部52間之接觸而向後推進。可在第2圖中觀察到，引動器18的後端64鄰接向前面對插管持器16的環狀肩部52之毗連部分，同時如所描述引動器18在彈簧22下的部分之後端與環狀肩部52稍微分離。此稍微分離造成由使用者所施加在柄44上之向後方向的力量集中對抗環狀肩部52之一側而非繞著周圍均勻分佈，此咸信可減低啟動縮回所需要的手動力量。When the fluid infusion or extraction procedure is completed, the user can apply the rearwardly directed pressure to the handle 44 while maintaining the outer cover 12 in the rest position (by clamping the textured outer surface portion thereof (available in Figure 1). Seen in the middle) or by pressing down on the selective flank (which may have been secured to the patient) to initiate retraction and retract the cannula 14. Manual pressure applied to the shank 44 causes the ejector 18 to move rearward relative to the outer shroud 12. It is desirable to initiate retraction when the cannula (typically a needle) is still inserted into the patient. When the actuator 18 is moved rearward, the insertion tube 16 and the insertion tube stopper 46 are also advanced rearward due to contact between the rear end 64 of the actuator 18 and the annular shoulder 52 of the insertion tube 16. As can be seen in Figure 2, the rear end 64 of the actuator 18 abuts the abutting portion of the annular shoulder 52 that faces forwardly of the insertion tube 16, while the portion of the actuator 18 below the spring 22 is as described The ends are slightly separated from the annular shoulder 52. This slight separation causes the force in the rearward direction exerted by the user on the shank 44 to concentrate against one side of the annular shoulder 52 rather than evenly distributed around the circumference, which reduces the manual force required to initiate retraction.
參照第3圖，因應引動器18的向後移動，插管持器栓46通過過渡區域(通過肩部30)及進入下部分26的較大直徑縮回腔36中。當插管持器栓46移動時，在插管持器栓46的外表面48與下部分26的內壁50間之摩擦力減低，及當插管持器栓46通過過渡區域及進入縮回腔36時，摩擦支撐力量完全消除。在使用者的手指力量(如透過引動器18之柄44施加)與壓縮彈簧22之偏向加壓力量的結合足夠減低摩擦支撐力量的點處，彈簧22會將插管持器16與插管持器栓46向後推入縮回腔36中，因此同步造成插管持器16將插管14的斜面尖端拉入外罩12內。將由熟習該項技術者在讀取此揭示後明瞭，引動器18應該足夠長，以便其相對於外罩12之移經範圍足以將插管持器栓46推過肩部30。Referring to Figure 3, in response to the rearward movement of the actuator 18, the insertion tube latch 46 passes through the transition region (through the shoulder portion 30) and into the larger diameter retraction chamber 36 of the lower portion 26. As the insertion tube stopper 46 moves, the friction between the outer surface 48 of the insertion tube stopper 46 and the inner wall 50 of the lower portion 26 is reduced, and when the insertion tube stopper 46 passes through the transition region and enters the retraction At chamber 36, the frictional support force is completely eliminated. At the point where the user's finger force (as applied through the handle 44 of the actuator 18) and the biasing force of the compression spring 22 are sufficient to reduce the frictional support force, the spring 22 holds the insertion tube 16 and the cannula The plunger 46 is pushed rearwardly into the retraction chamber 36, thereby causing the insertion tube 16 to pull the beveled tip of the cannula 14 into the outer cover 12. It will be apparent to those skilled in the art from reading this disclosure that the actuator 18 should be sufficiently long that its extent relative to the housing 12 is sufficient to push the cannula holder 46 over the shoulder 30.
如顯示在第3圖中，在縮回後，插管持器栓46想要毗連(或幾乎毗連)下部分26的後端罩42。下部分26想要製成可將插管14整體包含在下部分26內而不從前端32突出。在縮回後，引動器18的上邊緣阻擋了在插管14與在下部分26之上部中的孔洞38間之流體流動路徑。此防止流體從管子24(其仍然連接至外罩12的上部分28)漏出。As shown in FIG. 3, after retraction, the insertion tube stopper 46 is intended to adjoin (or nearly abut) the rear end cover 42 of the lower portion 26. The lower portion 26 is intended to be formed such that the cannula 14 is integrally contained within the lower portion 26 without protruding from the front end 32. After retraction, the upper edge of the actuator 18 blocks the fluid flow path between the cannula 14 and the aperture 38 in the upper portion of the lower portion 26. This prevents fluid from escaping from the tube 24 (which is still connected to the upper portion 28 of the outer cover 12).
本發明的另一個具體實例已揭示及描述在相關的第4及5圖中。參照第4圖，裝置70使用作為血液收集裝置或IV輸液組的零件較佳。裝置70包含一實質上矩形具有前壁72與向前凸出的圓錐形鼻74之外罩；具有開口狹長孔88的後壁92；側壁98；及協同性，實質上平坦的底壁104及與壁72,92及98互連之相應上壁(在截面圖中看不見)。與側壁98相對之底壁104與相應上壁(看不見)的邊緣在第4圖中看不見，但是其在前壁72與後壁92間延伸到稍微超過狹長孔88邊的位置處而移離開壁98最遠。滑動軌道94(可看見在前壁72背面上)整體形成如為前壁72的部分較佳。Another embodiment of the invention has been disclosed and described in related Figures 4 and 5. Referring to Fig. 4, the device 70 is preferably a component that is used as a blood collection device or an IV infusion set. The device 70 includes a substantially rectangular outer cover having a front wall 72 and a forwardly convex conical nose 74; a rear wall 92 having an open elongated opening 88; a side wall 98; and a synergistic, substantially flat bottom wall 104 and The respective upper walls of the walls 72, 92 and 98 are interconnected (not visible in cross-section). The bottom wall 104 opposite the side wall 98 and the corresponding upper wall (invisible) edge are not visible in Fig. 4, but extend between the front wall 72 and the rear wall 92 to a position slightly beyond the edge of the elongated hole 88. Leave the wall 98 farthest. It is preferred that the sliding track 94 (visible on the back side of the front wall 72) integrally form a portion such as the front wall 72.
如所顯示及描述，裝置70之外罩定義為一可構形縮回機構76及引動器96的結構。縮回機構76進一步包括具有較大直徑頭80之插管持器78及一對插管持器78施加向後方向的力量之偏向加壓成員較佳。較佳的偏向加壓成員為經壓縮的彈簧86。縮回機構76可從後面構形進入(在構形插管84與引動器96前較佳)外罩的前壁72、鼻74及滑動軌道94中。線圈狀彈簧86放置在插管持器78之向前延伸的末端上，然後將插管持器78***鼻74中直到繞著插管持器78配置的彈簧86之向前面對端對著鼻74的前端開口內之環狀肩部安置。當彈簧86被壓縮時，在頭80的向前面對表面上之環狀肩部82的一部分緊靠前壁72之向後面對的表面而與通過鼻74的開口毗連。當縮回機構76被適當地支撐(如藉由暫時鉗住插管持器78之向前延伸出鼻74的部分)住時，想要從外罩與壁98相對的那邊將引動器96***滑動軌道94中，及橫向移動至如顯示在第4圖中的位置，其中密封成員95提供一流體緊密密封而允許在插管持器78之頭80間流體流入引動器96的流體流動路徑100中。As shown and described, the outer cover of device 70 is defined as a structure that can be configured to retract mechanism 76 and actuator 96. The retraction mechanism 76 further includes a biasing member 78 having a larger diameter head 80 and a biasing member that applies a force to the rearward direction of the pair of cannula holders 78. A preferred biasing member is a compressed spring 86. The retraction mechanism 76 can be configured from the rear into the front wall 72, the nose 74 and the sliding track 94 of the outer cover (preferably prior to configuring the cannula 84 and the actuator 96). A coil spring 86 is placed over the forwardly extending end of the introducer holder 78, and the introducer holder 78 is then inserted into the nose 74 until the forward facing end of the spring 86 disposed about the insertion tube holder 78 faces An annular shoulder in the front end opening of the nose 74 is placed. When the spring 86 is compressed, a portion of the annular shoulder 82 on the forwardly facing surface of the head 80 abuts the rearward facing surface of the front wall 72 and abuts the opening through the nose 74. When the retraction mechanism 76 is properly supported (e.g., by temporarily clamping the portion of the insertion tube 78 that extends forwardly out of the nose 74), it is desirable to insert the actuator 96 from the side of the outer cover opposite the wall 98. In the track 94, and laterally moved to the position as shown in Fig. 4, wherein the sealing member 95 provides a fluid tight seal allowing fluid to flow into the fluid flow path 100 of the actuator 96 between the heads 80 of the insertion tube 78. .
引動器96為一伸長、實質上矩形的主體較佳，將其製成可與至少一條在外罩內部之導引或滑動軌道94滑動接合，以便引動器96容易在外罩內橫向移動。在引動器96內包含下列較佳：一由壁部分106,108所界定之同軸的流體流動路徑100；及一縮回艙102，其當引動器96在使用位置中時與插管84並列。有彈力的密封密封成員95(彈性O環或另一種類似有效的密封密封成員較佳)配置在通過引動器96之流體流動路徑100的前端處之凹處中，其可提供與插管持器78之變大的頭80之向後面對表面具有密封接合。將可觀察到的是，有彈力的密封密封成員95可密封以抵擋流體漏入或出流體流動路徑100。The actuator 96 is preferably an elongated, substantially rectangular body that is configured to slidably engage at least one of the guide or slide rails 94 within the housing such that the actuator 96 is easily moved laterally within the housing. The following preferably is included within the actuator 96: a coaxial fluid flow path 100 defined by the wall portions 106, 108; and a retraction chamber 102 that is juxtaposed with the cannula 84 when the actuator 96 is in the use position. A resilient seal seal member 95 (elastic O-ring or another similarly effective seal seal member is preferred) is disposed in the recess at the forward end of the fluid flow path 100 through the actuator 96, which can be provided with the intubation holder The enlarged head 80 of 78 has a sealing engagement with the surface toward the back. It will be observed that the resilient sealing seal member 95 can be sealed against fluid leakage into or out of the fluid flow path 100.
當如顯示在第4圖中般放置引動器96時，彈簧86維持在其壓縮狀態下及在向後面的方向中持續偏向加壓插管持器78，直到在裝置70使用後當引動器96選擇性再定位之時。一旦縮回機構76及引動器96構形在外罩內，插管84的後端可***插管78之軸孔中及被黏合或其它方面適當地被穩固。雖然無顯示，想要在插管84構形於插管持器78中後對其提供一可摩擦接合、可移除的保護蓋。When the actuator 96 is placed as shown in Fig. 4, the spring 86 is maintained in its compressed state and continues to bias the pressurized cannula 78 in the rearward direction until the actuator 96 is used after the device 70 is in use. Selective relocation time. Once the retraction mechanism 76 and the actuator 96 are configured within the housing, the rear end of the cannula 84 can be inserted into the shaft bore of the cannula 78 and be adhesively or otherwise suitably secured. Although not shown, it is desirable to provide a frictionally engageable, removable protective cover after the cannula 84 is configured in the cannula holder 78.
在使用前，裝置70藉由具彈性的管子部分90(其可藉由習知的方法經由狹長孔88***或其它方面附加至管子連結器103)連接至流體來源或流體儲槽較佳。當如顯示在第4圖中般放置引動器96時，在插管84與管子部分90間建立一實質上線性的流體流動路徑。管子連結器103可為在引動器96內之孔的一部分，其稍微成錐形以接收及摩擦接合管子部分90之自由端，或可藉由其它已知的方法(諸如例如，魯爾連接器、螺紋連接器、夾鉗、黏著劑及其類似物件)構形來附加管子部分。管子部分90為任何長度之具彈性的聚合管及合適於想要的用途之材料較佳。當如顯示在第4圖中般構形時，裝置70可使用來從欲經由插管排出的外部來源傳遞流體；或可經由該插管從外部來源抽取或抽出，隨後從與管子連結器103相對之管子部分90末端排出。Prior to use, the device 70 is preferably coupled to the fluid source or fluid reservoir by a resilient tube portion 90 (which may be inserted through the elongated holes 88 or otherwise attached to the tube connector 103 by conventional methods). When the actuator 96 is placed as shown in Figure 4, a substantially linear fluid flow path is established between the cannula 84 and the tube portion 90. The tube connector 103 can be part of a bore in the actuator 96 that is slightly tapered to receive and frictionally engage the free end of the tube portion 90, or can be by other known methods such as, for example, a luer connector , threaded connectors, clamps, adhesives, and the like are configured to attach the tube portion. The tube portion 90 is preferably a flexible polymeric tube of any length and a material suitable for the intended use. When configured as shown in Figure 4, the device 70 can be used to transfer fluid from an external source to be expelled via the cannula; or can be withdrawn or withdrawn from an external source via the cannula, and subsequently from the tube connector 103 The end of the tube portion 90 is discharged.
在使用後，藉由在與通過插管84及插管持器78的縱軸實質上垂直之方向上對引動器96施加手動力量，藉由將引動器96從其使用位置移動至其縮回位置來啟動縮回。參照第5圖，當引動器96橫向朝向壁98移動時，通過引動器96之流體流動路徑100橫向偏移至一不再與插管持器78的頭80相對之位置。同時，藉由經壓縮的彈簧86之偏向加壓力量將插管持器78推入引動器96的縮回腔102中對頭80作用，因此將插管84抽回外罩內。為了產生此結果，將明瞭的是，在背壁92與鼻74的前尖端間之距離必需足夠大以便至少將插管84的末端點接收進入鼻74中。同樣地，該未壓縮的彈簧86之長度想要為可將頭80維持成離鼻74之前端開口一段足夠的距離，使得插管84之尖端在縮回後不會再次從裝置70的前端突出，特別是若裝置70隨著插管指向下而旋轉至垂直位置時。After use, by applying manual force to the actuator 96 in a direction substantially perpendicular to the longitudinal axis through the cannula 84 and the cannula 78, the actuator 96 is moved from its position of use to its retraction. Position to initiate retraction. Referring to Figure 5, as the actuator 96 moves laterally toward the wall 98, the fluid flow path 100 through the actuator 96 is laterally offset to a position that is no longer opposite the head 80 of the cannula holder 78. At the same time, the intubation holder 78 is pushed into the retraction chamber 102 of the actuator 96 by the biasing force of the compressed spring 86 to act on the head 80, thereby withdrawing the cannula 84 back into the housing. To produce this result, it will be apparent that the distance between the back wall 92 and the front tip of the nose 74 must be sufficiently large to receive at least the end point of the cannula 84 into the nose 74. Similarly, the length of the uncompressed spring 86 is intended to maintain the head 80 a sufficient distance from the front end of the nose 74 such that the tip end of the cannula 84 does not protrude from the front end of the device 70 again after retraction. In particular, if the device 70 is rotated to a vertical position as the cannula is directed downward.

Retraction mechanism 118 preferably includes a needle container having a forwardly extending small diameter portion 106 and a large diameter head 108 disposed rearwardly of the small diameter portion 106. The compressed spring 116 is configured such that it slides over the small diameter portion 106 and abuts against the annular surface of the forward facing head 108. The sealing member (O ring 120 is preferred) is further described below.
參照第9圖，該縮回機構從後面***外罩112之頸136中，其中針頭容器的小直徑部分106經由在前端中之開口向前凸出。彈簧116可滑動地接合小直徑部分106，及彈簧116的向前端對著與在頸136內之前端開口毗連的環狀肩部安置。彈簧116的其它端緊靠頭108之環狀肩部。彈簧116被壓縮及藉由引動器114對著頭108所施加的相反力量維持在該預縮回位置中。引動器114相對於外罩112配置在其使用位置中，其中裝配圓凸128樞軸地***孔洞126中及接觸表面166緊靠外罩112之內表面而與凹進去的壁部分168毗連。引動器114包括由壁150,152所界限之流體流動路徑154及縮回腔164。在外罩112中提供空間124，以便當引動器114經再定位以終止流體流動及啟動縮回時可接收其一部分。Referring to Figure 9, the retracting mechanism is inserted into the neck 136 of the outer cover 112 from the rear, wherein the small diameter portion 106 of the needle container projects forwardly through the opening in the front end. The spring 116 slidably engages the small diameter portion 106 and the forward end of the spring 116 is disposed against an annular shoulder abutting the front end opening in the neck 136. The other end of the spring 116 abuts the annular shoulder of the head 108. The spring 116 is compressed and maintained in the pre-retracted position by the opposing force applied by the actuator 114 against the head 108. The actuator 114 is disposed relative to the outer cover 112 in its position of use with the mounting tab 128 pivotally inserted into the aperture 126 and the contact surface 166 abutting the inner surface of the outer cover 112 to abut the recessed wall portion 168. The actuator 114 includes a fluid flow path 154 and a retraction chamber 164 bounded by walls 150, 152. A space 124 is provided in the outer cover 112 to receive a portion of the mover 114 when it is repositioned to terminate fluid flow and initiate retraction.
隨著引動器114在此位置上，通過引動器114之流體流動路徑154配置成經由針頭容器與軸通道144及與針頭122的內部流體連通。密封成員120安置在凹處148中，其想要在壁150,152之向前端與針頭容器之頭108間提供流體緊密密封接合。此密封接合由頭108的環狀肩部146促進。管子連結器156想要在流體流動路徑154之後端處包括向外呈錐形的壁142，及採用此壁來接收及接合管子部分162(以虛擬的外形顯示)之末端。提供外罩112的凸出圓凸158(其設置成與縮回腔164之向前面對端毗連)，以防止引動器114不慎地從預縮回位置移動至縮回位置。實務上，想要在圓凸158與引動器114的面對表面160間之間隔少於在用於闡明目的之第9圖中所顯示者。As the actuator 114 is in this position, the fluid flow path 154 through the actuator 114 is configured to be in fluid communication with the shaft passage 144 and with the interior of the needle 122 via the needle container. The sealing member 120 is disposed in the recess 148 which is intended to provide a fluid tight sealing engagement between the forward end of the wall 150, 152 and the head 108 of the needle container. This sealing engagement is facilitated by the annular shoulder 146 of the head 108. The tube connector 156 is intended to include an outwardly tapered wall 142 at the rear end of the fluid flow path 154 and to receive and engage the end of the tube portion 162 (shown in a virtual outline). A raised circular projection 158 of the outer cover 112 is provided (which is disposed adjacent the forward facing end of the retracted cavity 164) to prevent the actuator 114 from inadvertently moving from the pre-retracted position to the retracted position. In practice, the spacing between the convex 158 and the facing surface 160 of the actuator 114 is less than that shown in Figure 9 for purposes of illustration.

Rotation on the shaft terminates the fluid flow by repositioning the actuator 114 relative to the housing 112. While some manual pressure is required to overcome the impedance of pushing the surface 160 past the knob 158 and moving the sealing member 120 through the head 108, it is desirable that the required force be readily applied by the adult user. It will again be observed that the resilient seal member 120 seal prevents fluid from leaking into or out of the fluid flow path 154.

Channels 144 of 108 are juxtaposed. Moreover, as soon as the wall 150 passes over the head 108, the retraction cavity 164 pivots into alignment with the opening through the neck 136, and the biasing force of the compressed spring 122 projects the needle container into the retraction chamber while simultaneously projecting the needle container into the retraction chamber. The tip of the needle 122 is withdrawn from the patient and into the housing 112 to avoid accidental needle sticks and to prevent reuse of the device 110.

隨著引動器316在顯示於第19圖中的位置，通過引動器316的流體流動路徑328配置成與通過針頭容器312之軸通道及與在針頭308內的軸通道258流體連通。彈性密封成員314想要在流體流動路徑328的向前端與針頭容器312的頭間提供流體緊密性密封接合。流體流動路徑328的後面部分想要包含錐形壁，以便如先前描述般接收及接合管子部分318之末端。想要凸出圓凸(如先前在相關的第15圖中對外罩226之圓凸235的描述)毗連位於縮回腔330的向前面對端，以防止引動器316不慎地從第19圖之預縮回位置移動至顯示在第20圖中的縮回位置。As the actuator 316 is shown in the position shown in FIG. 19, the fluid flow path 328 through the actuator 316 is configured to be in fluid communication with the shaft passage through the needle container 312 and with the shaft passage 258 within the needle 308. The elastomeric seal member 314 wants to provide a fluid tight sealing engagement between the forward end of the fluid flow path 328 and the head of the needle container 312. The rear portion of the fluid flow path 328 is intended to include a tapered wall to receive and engage the ends of the tube portion 318 as previously described. The convex protrusion (as previously described in the associated Fig. 15 of the outer cover 226) is adjacently located at the forward facing end of the retraction chamber 330 to prevent the actuator 316 from inadvertently from the 19th. The pre-retracted position of the figure moves to the retracted position shown in Fig. 20.
參照第20圖，在已經於任一方向中完成經由裝置300之流體傳遞至想要的程度後，容易地藉由對引動器接觸表面施加壓力(如由箭號338指示出)，使得引動器316在由箭號338所顯示出的方向上樞軸轉動，藉由引動器316相對於外罩304再定位而終止流體流動。在該引動器相對於外罩304再定位後(如顯示於第20圖)，在針頭308與管子連結器主體322間的流體流動被阻擋，及流體流動路徑328與通過鼻306之開口並列。再者，縮回腔330一經樞軸回轉成與開口通過外罩304的頸306同軸對準，經壓縮的彈簧308之偏向加壓力量會將針頭容器312推入縮回腔330中，同時從患者抽回針頭308的尖端及進入外罩304中，以避免意外的針刺及防止再使用，因此減低將流體輸送性病原體散佈至另一人士的相關可能性。Referring to Figure 20, after the fluid passing through the device 300 has been delivered to the desired level in either direction, the actuator is easily applied by applying pressure to the actuator contact surface (as indicated by arrow 338). 316 pivots in the direction indicated by arrow 338, terminating fluid flow by repositioning the actuator 316 relative to the outer cover 304. After the actuator is repositioned relative to the outer cover 304 (as shown in FIG. 20), fluid flow between the needle 308 and the tube connector body 322 is blocked, and the fluid flow path 328 is juxtaposed with the opening through the nose 306. Moreover, once the retraction chamber 330 is pivoted to be coaxially aligned with the opening through the neck 306 of the outer cover 304, the biasing force of the compressed spring 308 pushes the needle container 312 into the retraction chamber 330 while The patient withdraws the tip of the needle 308 and enters the outer cover 304 to avoid accidental needle sticks and prevent reuse, thereby reducing the likelihood of spreading fluid transport pathogens to another person.
如於本文中所揭示，全部的外罩、引動器、插管持器、保護蓋、端帽及管子連接器皆可由任何合適的材料製得，諸如例如，塑膠、金屬、陶瓷、玻璃或其類似物。對醫療應用(諸如IV輸液及血液收集)來說，使用模塑的聚丙烯較佳。類似地，依想要的用途或應用而定，合適於使用在本發明中之插管可由金屬、塑膠或陶瓷材料製得，且金屬較佳。所使用作為流體密封成員或插管持器栓之有彈力的零件想要由橡膠、其它彈性聚合物或經橡膠改質的塑膠製得。As disclosed herein, all of the outer cover, the actuator, the insertion tube holder, the protective cover, the end cap, and the tube connector can be made of any suitable material, such as, for example, plastic, metal, ceramic, glass, or the like.
